BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to roof top carriers for vehicles and, more particularly, to roof top carriers adapted to carry luggage and the like on vehicle roofs.

2. Description of the Prior Art

The prior art is replete with various forms of roof top carriers and these prior art roof top carriers are typically adapted for a specific application such as carrying and storage of boats, tents, wheelchairs and the like. These prior art forms of roof top carriers are typically complex in nature using cables, chains, multiple roller tracks and a typical list of the prior art patents may be as follows:

U.S. Pat. Nos. 2,395,173; 2,486,316; 2,668,646; 2,715,974; 3,756,648; 3,823,839; 3,905,499; 3,954,199; 3,999,673; 4,003,485; and 4,024,971; Canadian Pat. Nos. 672,587 and 994,719; British Pat. No. 1,248,970; Swiss Pat. No. 381,537; and West German OLS No. 2,150,124.

None of the above examples of the prior art are suitable for the present day automotive environment which is being shaped by the energy crisis and the resulting down-sizing of automobiles by the large automobile manufacturers. One of the major effects of this down-sizing is the reduction in the cargo carrying capability of automobiles. The present invention expands the cargo carrying capability of an automobile without materially affecting the performance characteristics of that automobile. It has the further distinct advantage of bringing the storage housing to the side of the automobile without any change in the vertical or horizontal orientation of that housing. Accordingly, luggage and like can be loaded and unloaded into the housing without any undue lifting which is particularly important in cases of older or infirmed people.

DESCRIPTION OF THE INVENTION

The present invention provides an improved roof top carrier 10 particularly adapted for vehicles and, more particularly, for automobiles 12 of all shapes and sizes. As before mentioned, significant and radial change is taking place in the automobile industry in that the overall size of the vehicles is being reduced. This "down-sizing" by most of the auto makers has been due in part to continual increasing costs of energy and, more particularly, gasoline. Accordingly, the roof top carrier 10 provides certain unique and beneficial characteristics which basically expand the cargo carrying capability of such down-sized automobiles without affecting the performance or safety characteristics of the automobile with which it is associated.

The roof top carrier 10 is basically supported by the automobile 12 roof 14. More specifically, the roof top carrier 10 is provided with a frame 16 which is suitably attached to the roof 14 by appropriate connecting means (not shown) such as suction cups, threaded fasteners, belted connectors, all of which are state of the art hardware. The roof top carrier 10 is provided with a housing 18 which is adapted to receive objects such as luggage (not shown) for the carrying thereof on the roof 14 of the automobile 12. The roof top carrier 10, as contemplated by the present invention, includes a transport means 20, which will be described in greater detail below. The transport means 20 is provided to transport the housing 18 from its stored position, as shown in FIG. 4 of the drawings, through an intermediate position, as shown in FIG. 3 of the drawings, to the loading and unloading position, both as shown in FIGS. 1 and 2 of the drawings. This is accomplished without any substantial change in the vertical or horizontal orientation of the housing 18, i.e., the housing may be moved through a complete cycle without ever changing its upright orientation with respect to the vehicle.

The transport means 20 which effects the transporting of the housing 18 generally includes first telescoping slidable arms 22 and second telescoping slidable arms 24. The first telescoping slidable arms 22, as their name implies, are telescopingly and slidably received by the frame 16. The manner in which the first telescoping slidable arms are received by the frame can be generally analogized to that structure which effects the slidable action of filing cabinets and the like, i.e., the first telescoping slidable arms are appropriately supported by bearings in a manner to be described below to move in and out of the frame 16 to transport the housing 18 horizontally away from the stored position, as shown in FIG. 4, to its intermediate position, as shown in FIG. 3.

The second telescoping slidable arms 24 are vertically supported by a frame member 26 which is carried by and affixed to the first telescoping slidable arms 22 as by welding, riveting or the like. Accordingly, as the first telescoping slidable arms 22 are moved out of the frame 16, the second telescoping slidable arms 24 are moved therewith within the frame member 26 which is affixed to the first telescoping slidable arms 22. In a typical roof top carrier 10, as contemplated by the present invention, there will be a frame 16, first and second telescoping slidable arms 22 and 24 and a frame member 26 provided both fore and aft of the housing 18 to provide equal support on each side thereof. The frames 16 will be parallel to each other and will be so positioned on the roof 14 to be perpendicular to the longitudinal axis of the automobile or vehicle 12 with which it is associated. Being so positioned on the roof top carrier 10, the frame members 16 will also be generally horizontal with respect to the vehicle roof 14.

As can best be seen in FIG. 3, the housing 18 can be moved horizontally by the first telescoping slidable arms 22 away from the frame 16 and its stored position, as shown in FIG. 4, to a point at which one of the first telescoping slidable arms 22 is slidably removed from the other of such telescoping slidable arms. At this point the housing 18 is free to be transported generally vertically downward by means of the second telescoping slidable arms 24 to the side of the automobile 12 to its loading and unloading position, as shown in both FIGS. 1 and 2. The horizontal travel of the housing 18 away from its stored position is limited by travel limiting means provided on the first telescoping slidable arms 22. More particularly, the travel limiting means includes a connecting rod 30 which is angularly disposed toward and connects the frame 16 to the vertical frame member 26. The connecting rod 30 is provided with a roller 32 which is journaled at its end toward the frame 16. The roller 32 is captured by and rolls within a substantially C-shaped opening 34 provided on substantially the entire length of the frame 16. The angularly disposed connecting rod 30 has another roller 36 journaled at its other end on the same side of the connecting rod 30 as the journaled roller 32. The roller 36 is captured by and rolls within a substantially C-shaped opening 38 provided on a portion less than the entire length of the frame member 26. As the housing 18 moves horizontally from its stored position, as shown in FIG. 4, to its horizontal extension, as shown in FIG. 3, the connecting rod 30 will move from a generally perpendicular position to an angularly diposed position with respect to the frame 16. During that movement roller 32 will track within the C-shaped opening 34 from a position beginning at the end of the C-shaped opening 34 opposite to that at which the housing 18 is traveling to the other end of the C-shaped opening 34 to be stopped thereby. Similarly, roller 36 will begin at the upper vertical end of the C-shaped opening 38 and will travel to the lower end of the C-shaped opening 38 to be stopped thereby. The action of the connecting rod 30 and its rollers 32 and 36 with the C-shaped openings 34 and 38 will both maintain the upright position of the housing 18 as it moves horizontally with respect to the roof 14 as well as limit the horizontal travel of the housing 18.

As before mentioned, the housing 18 in its horizontally extended position, as shown in FIG. 3, is free to be transported generally vertically downward by means of the second telescoping slidable arms 24 to the side of the automobile 12 to its loading and unloading position. As the housing 18 so moves vertically downward, the second telescoping slidable arms 24 will telescope outwardly from the frame member 26 to a point where the housing 18 comes to rest on a resilient means such as spring member 40 which is provided within the aft side 42 of the housing 18. The spring member 40 will encounter the upper side of the first telescoping slidable arms 22. The spring member 40 serves several purposes including the limiting of the vertically downward travel of the housing 18. In addition to that function, it provides a ready means to determine the weight of the objects that may have been added to the housing 18. As luggage, for example, is added to the housing 18, the spring member 40 will become more and more compressed. This direct relationship between the compression of the spring member 40 and the additional weight can be used to indicate the additional weight as well as provide an indication of an overweight situation. This could be accomplished by the provision of a pointer or some other color coded means (all not shown) which would indicate that point at which an excess of luggage has been added to the housing 18. In addition, a simple electrical circuit involving a connection to the automobile battery in series with a micro switch and an alarm could be utilized. As the weight again reaches a predetermined excessive level, the micro switch could be closed sounding the alarm possibly remote from the housing 18 such as within the automobile to warn of an excess luggage situation.

The housing 18 could be totally enclosed, i.e., the four sides and top and bottom. One or more of the sides or the top could be hingedly connected to the housing to allow ready access thereto. The housing 18 could be further provided with suitable locking means to both lock the hinged openings of the housing 18 as well as lock the entire housing 18 in its stored position, as shown in FIG. 4.

In addition, a power assist means (not shown) could be provided in which an electrical motor is connected in series to the automobile battery. The motor could be operatively connected to the housing 18 as by means of a simple sprocket and chain arrangement or drive belt arrangement (all not shown) which would assist in the movement of the housing 18 from its stored to its loading and unloading position and back again. Similarly, a counter weight mechanism (not shown) could be also operatively connected to the housing 18 to provide a counter weight force to the housing 18 when it is being lifted from its loading and unloading position to its stored position. As before mentioned, the first and second telescoping slidable arms 22 and 24 are generally analogous to the structure that effects the sliding action of filing cabinets and the like. As can be seen in FIG. 5, for example, the first telescoping slidable arms 22 slide upon and are supported by a series of spherical bearing members 44 which are held in position by cage members 46. Similarly, as can be seen in FIG. 6, the second telescoping slidable arms 24 slide upon and are supported by a series of spherical bearing members 48 which are held in position by cage members 50.

There is thus provided a roof top carrier embodying significant and important advantages over the prior art forms of roof top carriers. The roof top carrier of the present invention significantly expands and enlarges the luggage carrying capacity of automobiles without any significant affect on the performance or safety characteristics of the automobile. It provides for easy loading and unloading and storage of luggage without the use of any special equipment such as ladders or tools. It can be safely and securely locked in its stored position and can be fully enclosed to protect luggage from the elements. In its totality it offers a wide range of advantages not even contemplated by the prior art.

It is to be noted that the present invention is not to be limited to the specific details as herein described but is capable of other modifications and changes without departing from the spirit and scope of the appended claims.
